But Mourinho has defended his club’s conduct, saying: “The transfer window is open, when it is open every club and every player is open to bids.

“Bids come for our players, we make bids for other players and the process can be so simple.

“I would advise Roberto to do the same thing as I do. If I get an offer for one of my players and I don’t want to accept any offer I say I don’t accept any offer, so he can make it very, very easy.

“If today I receive a bid for (Cesc) Fabregas in two minutes I will say I don’t accept any bid, game over, that’s it.”

The Chelsea manager added: “If we made a bid it is because we like the player, we don’t make bids for players we don’t like, but we respect Everton and respect every club that has a player and it is up to them – everything is in their hands.”

Speaking at a sponsor’s event on Friday, Stones said: “I am very happy at Everton.”
